FIG. 1 is a diagram illustrating an ultrasound apparatus 1000 according to exemplary embodiments. The ultrasound apparatus 1000 may include a display unit 141, an input unit 103, and a controller (not shown). The input unit 103 may further include a predetermined screen, or a display panel or a touch screen 106 for visually providing information to a user, in addition to an input device for a user to input data, commands or requests to the ultrasound apparatus 1000. Also, the display unit 141 may operate as a touch screen receiving a user's touch input.

Referring to FIG. 1 , the display unit 141 of the ultrasound apparatus 1000 may display an ultrasound image 130 on the touch screen 106. Also, the ultrasound apparatus 1000 may display on the ultrasound image 130 a measuring device image 110 for measuring an object included in the ultrasound image 130.

The ultrasound apparatus 1000 may determine one from among a plurality of measuring devices, based on a user input that is input through the input unit 103. For example, the ultrasound apparatus 1000 may determine one from among the plurality of measuring devices, when receiving the user input selecting the measuring device.

When the ultrasound apparatus 1000 determines one from among the plurality of measuring devices, the ultrasound apparatus 1000 may display a measuring device image 110 corresponding to the measuring device, on the ultrasound image 130. For example, when the ultrasound apparatus 1000 receives a user input selecting an icon 105 indicating a length measuring device for measuring a length of a specific part of an organ or a specific bone, the ultrasound apparatus 1000 may display a length measuring device image 110 corresponding to the length measuring device, on the ultrasound image 130.

The measuring device image 110 may include a measuring point which indicates a point on the ultrasound image that is to be measured. Also, the measuring device image 110 may include an adjusting portion for receiving a user input adjusting a position of the measuring point. In this case, the measuring point may be disposed apart from the adjusting portion. Accordingly, the user may precisely configure the measuring portion, without covering with a finger the measuring portion on the ultrasound image.

Also, the ultrasound apparatus 1000 may receive a touch input changing a position of the adjusting portion.

Also, the ultrasound apparatus 1000 may adjust a position of at least one of the plurality of measuring points, based on the changed position of the adjusting portion, and may obtain a measurement value, based on a position of the plurality of measuring points including the at least one measuring point, the position of which is adjusted.

Also, the ultrasound apparatus 1000 may display the obtained measurement value.

When the ultrasound apparatus 1000 receives a touch input with respect to the adjusting portion, the ultrasound apparatus 1000 may change a position of the adjusting portion and the measuring point, in the ultrasound image, by changing at least one of a position and a shape of the measuring device image 110.

For example, when receiving the touch input with respect to the adjusting portion, the ultrasound apparatus 1000 may determine the position of the measuring point based on the position of the adjusting portion. Also, when the position of the measuring point is determined, the ultrasound apparatus 1000 may display the measuring point by shifting the measuring point in the measuring device image. In this case, the ultrasound apparatus 1000 may shift the measuring point by changing at least one of the shape and the position of the measuring device image 110.

Also, when the position of the measuring point is determined, the ultrasound apparatus 1000 may calculate a measurement value with respect to a measurement item corresponding to a measuring device that is selected based on the determined position of the measuring point. The measurement item may include information associated with a length, an angle, an area, and a volume.

Shapes of a measuring device image for measuring a distance may be a physical vernier caliper or a physical pincette. Also, shapes of a measuring device image for measuring an area may be the physical scissors. Also, shapes of a measuring device image for measuring an outline may be a physical pen. Accordingly, the user may instinctively recognize an interface method with respect to the measuring device.

FIG. 2 is a flowchart of a method of obtaining a measurement value via the ultrasound apparatus 1000, according to an embodiment.

The ultrasound apparatus 1000 may display a measuring device image including a plurality of measuring points, which indicate points on an ultrasound image that are to be measured, and an adjusting portion for adjusting the plurality of measuring points, on the ultrasound image, in operation S210.

The ultrasound apparatus 1000 may receive a user input selecting one from among a plurality of measuring devices.

The measuring devices may refer to a measuring application which receives a user input configuring a position of the measuring point, and provides a measurement value with respect to an object in an ultrasound image based on the position of the measuring point, by using an image indicating a point on an ultrasound image that is to be measured as a medium.

The ultrasound image may be at least one selected from a B (brightness) mode image indicating a magnitude of an ultrasound echo signal reflected from an object as a brightness, a C (color) mode image indicating a speed of a moving object as a color by using a Doppler effect, a D (Doppler) mode image indicating an image of the moving object as a spectrum by using the Doppler effect, an M (motion) mode image indicating a motion of an object according to time in a predetermined position, and an E (elastic) mode image indicating a difference in a reaction between when compression is and is not applied to an object, as an image. However, the ultrasound image is not limited thereto. Also, the ultrasound image may be a two-dimensional image, a three-dimensional image, or a four-dimensional image. The ultrasound apparatus 1000 may obtain the ultrasound image by photographing an object. Also, the ultrasound apparatus 1000 may receive the ultrasound image from an external device.

The ultrasound apparatus 1000 may determine one from among a plurality of measuring devices, based on a user input selecting one from among the plurality of measuring devices for measuring the object in the ultrasound image. For example, the ultrasound apparatus 1000 may provide a measuring device selection menu for selecting one from among the plurality of measuring devices. The ultrasound apparatus 1000 may display the measuring device selection menu together with the ultrasound image on one screen. Also, the ultrasound apparatus 1000 may display the measuring device selection menu on a separate screen that is different from a touch screen on which the ultrasound image is displayed.

Also, the ultrasound apparatus 1000 may determine one from among the plurality of measuring devices, based on a user input selecting one from among a plurality of measurement items. The measurement item may include a length, a width, or an angle, but it is not limited thereto. When the ultrasound apparatus 1000 receives the user input selecting one measurement item, the ultrasound apparatus 1000 may determine a measuring device that is predetermined in correspondence to the selected measurement item.

Also, the ultrasound apparatus 1000 may determine one from among the plurality of measuring devices, based on a pattern of a user input. For example, when the ultrasound apparatus 1000 receives a user input touching two points on a touch screen and dragging the two points in opposite directions, the ultrasound apparatus 1000 may determine an oval measuring device as the measuring device. Also, when the ultrasound apparatus 1000 receives a user input touching two points on the touch screen and rotating one point, the ultrasound apparatus 1000 may determine a degree measuring device as the measuring device.

The ultrasound apparatus 1000 may display on the ultrasound image a measuring device image corresponding to the selected measuring device.

The measuring device image refers to a point that is to be measured in the ultrasound image, and may refer to an image medium of a graphic user interface for receiving a user input configuring a position of the measuring point. The measuring device image may be pre-stored in correspondence to the measuring device.

When the ultrasound apparatus 1000 determines one from among the plurality of measuring devices, the ultrasound apparatus 1000 may display a measuring device image corresponding to the determined measuring device, on the ultrasound image.

For example, when a vernier caliper measuring device is determined, the ultrasound apparatus 1000 may display a vernier caliper measuring device image on the ultrasound image. Also, when a pincette measuring device is determined, the ultrasound apparatus 1000 may display a pincette measuring device image on the ultrasound image. Also, when a scissors measuring device is determined, the ultrasound apparatus 1000 may display a scissors measuring device image on the ultrasound image.

The measuring device image may include a plurality of measuring points which indicate points on the ultrasound image that are to be measured. The points on the ultrasound image that are to be measured may be points in the ultrasound image, which is a reference for measurement. The measuring points on the ultrasound image may be configured by the user via the measuring device image. A position of the plurality of measuring points in the measuring device image may be pre-determined in correspondence to the measuring device image. For example, the plurality of measuring points in the measuring device image having a shape of the scissors, the plurality of measuring points may be both edges of the scissors.

Also, the measuring device image may include an adjusting portion for adjusting the position of the plurality of measuring points. Also, a position of the adjusting portion in the measuring device image may be pre-determined in correspondence to the measuring device image. For example, the adjusting portion in the measuring device image having the shape of the scissors may be a handle portion of the scissors.

The adjusting portion may be disposed not to overlap the plurality of measuring points in the measuring device image. For example, the adjusting portion may be apart from the plurality of measuring points in the measuring device image by a predetermined distance.

Also, the ultrasound apparatus 1000 may display the measuring device image such that the adjusting portion may be distinguished from other portions of the measuring device image. For example, the ultrasound apparatus 1000 may display the adjusting portion in a different color from other portions of the measuring device image.

The ultrasound apparatus 1000 may display the measuring device image half-transparently so that a portion of the ultrasound image, which overlaps the measuring device image, is not covered by the measuring device image.

The ultrasound apparatus 1000 may receive a touch input changing a position of the adjusting portion of the measuring device image on the ultrasound image, in operation S220.

The ultrasound apparatus 1000 may receive a touch and drag input with respect to the adjusting portion in the measuring device image. For example, the ultrasound apparatus 1000 may receive the input of touching the adjusting portion via a finger or an electronic pen, and dragging the finger or the electronic pen to another position in a screen, while maintaining the state of touching. When the ultrasound apparatus 1000 receives the touch and drag input, the ultrasound apparatus 1000 may move the adjusting portion along the drag.

In this case, the ultrasound apparatus 1000 may move the adjusting portion in the measuring device image by changing at least one of a position and a shape of the ultrasound image.

In operation S230, the ultrasound apparatus 1000 may adjust a position of at least one of the plurality of measuring points based on the changed position of the adjusting portion, and may obtain a measurement value based on a position of the plurality of measuring points including the at least one measuring point, the position of which is adjusted.

When the position of the adjusting portion is changed in the ultrasound image, the ultrasound apparatus 1000 may determine the position of the measuring point based on the position of the adjusting portion.

For example, the ultrasound apparatus 1000 may determine a point that is apart from a central point of the adjusting portion, by a pre-determined distance, as the measuring point. Also, the ultrasound apparatus 1000 may determine a point that is apart from a pre-determined adjusting point in the adjusting portion, by a pre-determined distance, along a direction of a straight line connecting the adjusting point and at least one reference point in the ultrasound image, as the measuring point. In this case, the ultrasound apparatus 1000 may adjust a position of at least one of the plurality of measuring points by changing at least one of a position and a shape of the measuring device image.

For example, the ultrasound apparatus 1000 may adjust the position of the at least one of the plurality of measuring points by adjusting a length of the measuring device image. Also, for example, the ultrasound apparatus 1000 may adjust the position of the at least one of the plurality of measuring points by rotating the measuring device image. Also, when the measuring device image is formed of two partial images crossing each other, based on a reference point, the ultrasound apparatus 1000 may adjust the position of the at least one of the plurality of measuring points by rotating the two partial images based on the reference point.

The ultrasound apparatus 1000 may obtain a measurement value with respect to a measurement item corresponding to a selected measuring device, based on the position of the plurality of measuring points.

When the position of the at least one of the plurality of measuring points is adjusted, the ultrasound apparatus 1000 may obtain the measurement value with respect to the measurement item corresponding to the selected measuring device, based on the position of the plurality of measuring points in the ultrasound image.

For example, the ultrasound apparatus 1000 may measure a distance between two measuring points on the ultrasound image, based on a position of the two measuring points on the measuring device image. The ultrasound apparatus 1000 may generate a circle having a straight line connecting the two measuring points as a diameter, based on the position of the measuring points, and may calculate at least one of the diameter, a circumferential length, and an area of the generated circle.

In this case, the ultrasound apparatus 1000 may convert a scale on the ultrasound image into a scale on a real object, in order to calculate a length, an area, and a volume.

Also, the ultrasound apparatus 1000 may configure an interest area on the ultrasound image based on the position of the plurality of measuring points and obtain a measurement value with respect to the configured interest area. For example, the ultrasound apparatus 1000 may configure a gate on the ultrasound image based on a position of two measuring points and measure a blood flow speed of an area indicated by the gate.

The ultrasound apparatus 1000 may display the obtained measurement value in operation S240.

The ultrasound apparatus 1000 may display the obtained measurement value on the measurement device image.

Also, the ultrasound apparatus 1000 may receive a touch input ending a touch and drag with respect to the adjusting portion. When receiving the touch input ending the touch and drag with respect to the adjusting portion, the ultrasound apparatus 1000 may display a button image for storing a measurement value, corresponding to the ultrasound image, on the ultrasound image.

Also, when receiving the touch input ending the touch and drag, the ultrasound apparatus 1000 may delete the measuring device image on the touch screen and may display a button image for re-adjusting the position of the plurality of measuring points, on the ultrasound image.

When the ultrasound apparatus 1000 determines the position of the adjusting point, the ultrasound apparatus 1000 may determine a position of a point that is apart from a first adjusting point by a pre-determined distance and a position of a point that is apart from a second adjusting point by a pre-determined distance, the points apart from the first and second adjusting points being from among a plurality of points on a straight line connecting the first and second adjusting points, and then may determine points that are respectively apart from the determined positions by a pre-determined distance, along a direction perpendicular to the straight line, as the measuring point.

The ultrasound apparatus 1000 may adjust a position of at least one of two measuring points in the vernier caliper measuring device image, in operation S450.

The ultrasound apparatus 1000 may adjust the position of the at least one of the two measuring points, by changing at least one of a position and a shape of the vernier caliper measuring device image.

For example, the ultrasound apparatus 1000 may adjust the position of the at least one of the two measuring points, by rotating the vernier caliper measuring device image. Also, the ultrasound apparatus 1000 may adjust the position of the at least one of the two measuring points, by lengthening the vernier caliper measuring device image.

The ultrasound apparatus 1000 may calculate a distance between the two measuring points based on the determined position of the two measuring points, in operation S460.

The ultrasound apparatus 1000 may display the calculated distance, in operation S470.

FIG. 5A is a view for describing a method of providing a distance measuring function via a vernier caliper measuring device, via the ultrasound apparatus 1000, according to an embodiment.

Referring to FIG. 5A, when the vernier caliper measuring device is selected, the ultrasound apparatus 1000 may determine a measuring point and an adjusting portion on an ultrasound image.

For example, when receiving a user input selecting the icon 341 indicating the vernier caliper measuring device in the measuring device selection menu 340 illustrated in FIG. 3 , the ultrasound apparatus 1000 may obtain a position of two measuring points 511 and 513 and the adjusting portion 530 on the ultrasound image. The adjusting portion 530 may include a first adjusting portion 531 and a second adjusting portion 533. A user may configure the measuring points 511 and 513 at a part that is to be measured in an object in the ultrasound image. For example, when the object is a fetus, and the measuring part is a nuchal translucency (NT) of the fetus, the user may locate the measuring points 511 and 531 at two end points of the NT. In this case, the user may move the first and second adjusting portions 531 and 533 to locate the measuring points 511 and 513 at the measuring part that is to be measured.

In detail, the measuring points 511 and 513 may be points on the ultrasound image, which is a reference for measurement. Also, the first and second adjusting portions 531 and 533 may be an area on the ultrasound image that receives a user's touch input for changing the location of the measuring points 511 and 513. Default locations of the two measuring points 511 and 513 and the adjusting portion 530 may be pre-determined in correspondence to the vernier caliper measuring device.

The vernier caliper measuring device may be a device for calculating a distance between the two measuring points 511 and 513. The ultrasound apparatus 1000 may calculate the distance between the two measuring points 511 and 513 based on the obtained location of the two measuring points 511 and 513.

When the ultrasound apparatus 1000 receives a touch and drag input with respect to the adjusting portion 530, the ultrasound apparatus 1000 may move the adjusting portion 530 along the dragged area. In this case, the ultrasound apparatus 1000 move the adjusting portion 530 by changing at least one of a shape and a position of the adjusting portion 530.

The first adjusting portion 531 may be configured to move above and below. Also, the second adjusting portion 533 may be configured to move above and below or to rotate based on a first adjusting point 521. Also, both of the adjusting portions 531 and 533 may simultaneously move in a parallel direction.

Other areas of the adjusting portion 530, except for the first adjusting portion 531 and the second adjusting portion 533, may be areas for the two measuring points 511 and 513 and the adjusting portion 530 to simultaneously move in the parallel direction.

When the adjusting portion 530 moves, the ultrasound apparatus 1000 may determine a position of the measuring points 511 and 513 based on the position of the adjusting portion 530. For example, the ultrasound apparatus 1000 may determine a position of adjusting points 521 and 523 based on a position of the first adjusting portion 531 and the second adjusting portion 533. The adjusting points 521 and 523 may be a point in the ultrasound image, which is becomes a reference point for determining the position of the measuring points 511 and 513. The position of the adjusting points 521 and 523 may be a central point of the first adjusting portion 531 and the second adjusting portion 533.

Also, when the position of the first adjusting portion 531 and the second adjusting portion 533 changes in the ultrasound image, the ultrasound apparatus 1000 may determine a position of a point 526 that is apart from the first adjusting point 521 by a pre-determined distance and a position of a point 527 that is apart from the second adjusting point 523 by a pre-determined distance, the points 526 and 527 apart from the first and second adjusting points 521 and 523 being from among a plurality of points on a straight line 525 connecting the first and second adjusting points 521 and 523, and then may determine the points 511 and 513 that are respectively apart from the determined positions 526 and 527 by a pre-determined distance, along a direction perpendicular to the straight line 525, as the measuring point. Accordingly, the measuring points 511 and 513 may be located at the position that is apart from the adjusting portions 531 and 533, by the pre-determined distance.

As illustrated in FIG. 5A, since the adjusting portion 530 is spaced apart from the measuring points 511 and 513, the measuring points 511 and 513 may be precisely configured without being covered by a finger, when the user configures the measuring points 511 and 513 by touching a random point in the adjusting portion 530 on a touch screen.

Also, when the position of the first adjusting portion 531 and the second adjusting portion 533 is changed in the ultrasound image, the ultrasound apparatus 1000 may store the changed position of the first adjusting portion 531 and the second adjusting portion 533 and the calculated position of the measuring points 511 and 513.

FIG. 5B is a view for describing a method of displaying a vernier caliper measuring device image 510 corresponding to a vernier caliper measuring device via the ultrasound apparatus 1000, according to an embodiment.

Also, the vernier caliper measuring device image 510 may include an adjusting portion 555 indicating an adjusting area. The adjusting portion 555 may include a first adjusting portion 557 indicating a position of a first adjusting area and a second adjusting portion 559 indicating a position of a second adjusting area.

The measuring points are located apart from the adjusting portion 555 by a pre-determined distance, and thus, the adjusting portion 555 indicating the adjusting area may be displayed at a location that is apart from the measuring points by the pre-determined distance.

The vernier caliper measuring device image 510 may have a physical shape of a vernier caliper. For example, the adjusting portion 555 may correspond to an area of a bar shape. Also, the two measuring points 511 and 513 may be located to be apart from the adjusting portion 555 by a pre-determined distance.

Also, when the adjusting portion 555 and the measuring points 511 and 513 are changed by a user's touch input, the ultrasound apparatus 1000 may change at least one of a position and a shape of the vernier caliper measuring device image 510 such that the adjusting portion 555 in the vernier caliper measuring device image 510 is located on the adjusting area and the two measuring points 511 and 513 indicate the measuring points.

Accordingly, a user may recognize a measuring point configured on the ultrasound image and a position of the adjusting area 530, from the vernier caliper measuring device image 510 displayed on the ultrasound image. Also, the ultrasound apparatus 1000 may receive a touch input with respect to the adjusting area 530, by receiving a touch input moving the adjusting portion 555 in the vernier caliper measuring device image 510. For example, the position of the first adjusting area may be moved along an area touched by the user. The ultrasound apparatus 1000 may receive a user's touch input moving the position of the first adjusting portion 557 by displaying the first adjusting portion 557 on the moved first adjusting area.

When receiving the touch input touching and dragging the second adjusting portion 559, the ultrasound apparatus 1000 may adjust a position of two measuring points 511 and 513 in the ultrasound image by changing at least one of a position and a shape of the vernier caliper measuring device image 510.

For example, the ultrasound apparatus 1000 may receive the touch input rotating the second adjusting portion 559 based on the first adjusting point 521 that is the center of the first adjusting portion 557. When receiving the touch input rotating the second adjusting portion 559, the ultrasound apparatus 1000 may determine a position of the second adjusting point 523 based on the position of the second adjusting portion 559. When the position of the second adjusting point 523 is determined, the ultrasound apparatus 1000 may determine the position of the two measuring points 511 and 513, based on the first adjusting point 521 and the determined position of the second adjusting point 523.

Also, the ultrasound apparatus 1000 may calculate the diameter, the circumferential length, and the area of the circle area 953 based on the obtained position of the measuring points 911 and 913.

When receiving a touch and drag input with respect to the adjusting areas 961 and 963, the ultrasound apparatus 1000 may move the adjusting areas 961 and 963 along the dragged area. In this case, the ultrasound apparatus 1000 may move the adjusting areas 961 and 963 by changing the position of the adjusting areas 961 and 963.

Also, when the position of the adjusting areas is changed by the user's input, the ultrasound apparatus 1000 may determine the position of the measuring points 911 and 913, based on the position of the adjusting areas 961 and 963.

For example, the ultrasound apparatus 1000 may determine a position of two adjusting points 921 and 923, based on the position of the first adjusting area 961 and the second adjusting area 963. The position of the two adjusting points 921 and 923 may be pre-determined in the adjusting areas 961 and 963. The two adjusting points 921 and 923 may include the first adjusting point 921 in the first adjusting area 961 and the second adjusting point 923 in the second adjusting area 963.
